Question

(iii) 2x2 +513x +6=0​

Answer 1

Answer:

x=-10/513

Step-by-step explanation:

2×2=4

so,

4+ 513x +6=0

10+513x=0

513x=-10

x=-10/513

Answer 2

Step-by-step explanation:

little correction : 2x²+513x+6=0

(I think you missed to type in the form of quadratic equation.)

I am using here formula method.

2x²+513x+6=0

Comparing 2x²+513x+6=0 with ax²+bx+c=0

we get,

a=2

b=513 and

c=6

b²-4ac = 513²- 4×2×6

=263,121

$x = (- b ±\sqrt{b^{2} - 4ac } ) \div 2a$

$( - 513± \sqrt{263121} ) \div( 2 \times 2)$

$( - 513±512.9) \div 4$
